An Amazon Prime Membership has a host of benefits and in my opinion if you order a lot from Amazon the Amazon prime membership is well worth the monthly or yearly cost.
With an Amazon Prime Membership you get benefits such as FREE fast shipping for eligible purchases, streaming of movies, TV shows and music, exclusive shopping deals and selection, unlimited reading etc.
There's much more than that and the list of things available for an Amazon Prime Member can be found on Amazons website on the Amazon Prime Membership page.
If you signup for Amazon Prime it's recommended to sign up for the yearly membership and pay yearly because it's cheaper.
I order a lot from Amazon and the Amazon Prime Membership is worth it to me.
But if you only order a few things per year or every other month then it may not be worth it but there are other benefits to the Amazon prime membership other than just Free Fast Shipping.
